There’s a new bill in Congress that would threaten your right to free expression online. If that weren’t enough, it could also put small Internet businesses in danger of catastrophic litigation.

Don’t let its name fool you: the Stop Enabling Sex Traffickers Act (SESTA, S. 1693) wouldn’t help punish sex traffickers. What the bill would do (PDF) is expose any person, organization, platform, or business that hosts third-party content on the Internet to the risk of overwhelming criminal and civil liability if sex traffickers use their services. For small Internet businesses, that could be fatal: with the possibility of devastating litigation costs hanging over their heads, we think that many entrepreneurs and investors will be deterred from building new businesses online.

Make no mistake: sex trafficking is a real, horrible problem. This bill is not the way to address it. Lawmakers should think twice before passing a disastrous law and endangering free expression and innovation.
